Ya I get it that it all depends on your personal preferences but I remember reading some where that it should be before and modulation effects. So if I have Delay, Chorus runn it need to be before those type of effects.

As per the BBE manual

SET-UP:---------------THe BBE is connected into the chain in series with the signal path the same way a graphic EQ or limiter would be connected. The output of a mixer, pre-amp or other sound source feeds the input of the Sonic Maximizer as an echo sned device like digital reverb is not recommended as the processed effect is not fully realized when summed with the original source audio."
